William E. Caplin (born 1948) is an American music theorist who lives and works in Montreal, Quebec, Canada, where he is a James McGill Professor at the Schulich School of Music of McGill University. Caplin served as president of the Society for Music Theory from 2005 to 2007 and was its vice-president from 2001 to 2003. [1] His earlier work concentrated on the history of music theory, [2] but he is best known for a series of articles and two books on musical form in European music around 1800. The first of those books, Classical Form: A Theory of Formal Functions for the Music of Haydn, Mozart, and Beethoven [3] has been widely influential and was a major factor in the revival of interest in musical form in North-American music theory. [4]
Classical Form, along with a more recently published, lengthy textbook intended for both undergraduate and graduate levels, [5] expounds a theory and analytical method for the music of the "high Classical" era (roughly, the two decades before and after 1800). The theory is grounded in eighteenth-century compositional pedagogy [6] and in work by Arnold Schoenberg and his pupil Erwin Ratz. [7] Broadly, the theory can be understood as "a generalized taxonomy of Classical form gleaned from a large repertory of works rather than the description of the organic wholeness or the uniqueness of events in any one work." [8]
Schoenberg’s concept of the "basic idea" (here understood as a two-measure unit) [12] and his distinction between period and sentence—two models for themes—are the foundation for a theory based on a dichotomy between "tight-knit" and "loose" designs and on "beginning," "middle," and "end" functions. The core figure is the theme (understood paradigmatically as eight bars in length), but formal functions can be extended outward to form sections and entire movements. "Tight-knit" themes and small forms are the sentence, period, hybrid, and compound (16-bar) themes, small ternary, and small binary. "Looser formal regions" are the subordinate theme, transition, development, recapitulation, and coda. [13]
The period is the symmetrical or balanced design familiar from traditional form theory: an antecedent phrase with two contrasting ideas is followed by a consequent phrase that repeats (or slightly varies) the initial two-bar idea and adds a cadential idea to close. The sentence is a progressive or developmental design, where a presentation phrase consists of an idea and its repetition (often varied or transposed) followed by a continuation phrase that, ideally, fragments the initial idea by breaking it into one-bar motives and thereby accelerating movement toward the cadence. The less common hybrid themes mix the components in variously different ways (for example, the antecedent + continuation theme).
The theme types:
For hybrid 2: "cadential" refers to a phrase where a typical progression in a cadence (usually just two bars) is stretched over the entire phrase. Often this function is filled by the Expanded Cadential Progression (ECP) or I 6–ii 6–V–I. For hybrids 3 and 4: the compound basic idea is itself a hybrid: it has the antecedent's basic idea & contrasting idea pair, but it has the presentation's (usually) simple tonic prolongation. From these examples it can be seen that harmony has a powerful, often determining, role in Caplin's theory.
Compound themes are of two types: the 16-measure period, which is the same as the traditional double period, and the 16-measure sentence. The 16-measure period opens with an antecedent consisting of any eight-bar theme, which ends with a half cadence (HC) rather than a perfect authentic cadence (PAC). The eight-bar consequent repeats the opening but adjusts the cadence to a PAC. The 16-measure sentence is paradigmatically an eight-bar presentation, consisting of a compound basic idea and its repetition, followed by an eight-bar continuation with the typical features of fragmentation and sequence.
In larger contexts in Classical-era music, passages of tight-knit and loose-knit functions tend to alternate, the tight-knit units being represented by the themes above, the loose knit units by isolated phrases, model-sequence groups, "standing on the dominant," and other entities.
Pragmatically, the "strict definition of formal categories [is] applied with ‘considerable flexibility’ in analysis." [15] Thus, data for a set of analyses could be read as objective information but could just as easily be taken as a catalogue of the analyst’s choices. The assignment of labels for thematic elements often involves a judgment call. [16] The form-function theory, in other words, is both taxonomic and interpretative; it is from balancing the two that one can learn the most about the repertoires under analysis. The theory has, nevertheless, been criticized for a "zeal for exhaustive theoretical and terminological rigor" that can interfere with that flexibility in analysis, and specifically for its "dogged adherence to a rigidly quadratic conception of grouping structures" [source needed, linked source does not contain any of these quotes]; that is, to ideas defined as two bars and themes defined as eight bars. [17] A related criticism is Caplin's "tendency to substitute [a formal/functional] archetype for the music in question as the point of reference for analytical discussion." [18]
Although intended for, and derived specifically from, the music of Haydn, Mozart, and Beethoven, the theory of formal functions has been extended by various authors, mostly to later repertoires and largely in connection with the sentence paradigm (notably, Schubert, Schumann, Wagner, Schoenberg, and music in film) but occasionally earlier as well (especially J.S. Bach). See "Further reading" below.
In German-speaking discourse, Caplin's understanding of "Formfunktionen" (formal functions) and the coupling of "formal functions" and "loose" designs has been criticized as dogmatic. [19]
The Classical period was an era of classical music between roughly 1750 and 1820.
Sonata form is a musical structure generally consisting of three main sections: an exposition, a development, and a recapitulation. It has been used widely since the middle of the 18th century.
Binary form is a musical form in 2 related sections, both of which are usually repeated. Binary is also a structure used to choreograph dance. In music this is usually performed as A-A-B-B.
Erwin Ratz was an Austrian musicologist and music theorist. He is known especially for his work as president of the Gustav Mahler Gesellschaft and for his book Einführung in die musikalische Formenlehre. During Nazi rule, he saved the lives of several Austrian Jews by sheltering them in his apartment for a number of years.
In Western musical theory, a cadence is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards. A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase. A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives. While cadences are usually classified by specific chord or melodic progressions, the use of such progressions does not necessarily constitute a cadence—there must be a sense of closure, as at the end of a phrase. Harmonic rhythm plays an important part in determining where a cadence occurs. The word "cadence" sometimes slightly shifts its meaning depending on the context; for example, it can be used to refer to the last few notes of a particular phrase, or to just the final chord of that phrase, or to types of chord progressions that are suitable for phrase endings in general.
In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these.
In music, development is a process by which a musical idea is transformed and restated in the course of a composition. Certain central ideas are repeated in different contexts or in altered form so that the listener can consciously or unconsciously compare the various statements of the idea, often in surprising or ironic manners. This practice has its roots in counterpoint, where a theme or subject might create an impression of a pleasing or affective sort, but delight the mind further as its contrapuntal capabilities are gradually unveiled.
Ludwig van Beethoven's String Quartet No. 11 in F minor, Op. 95, from 1810, was his last before his late string quartets. It is commonly referred to as the "Serioso," stemming from his title "Quartett[o] Serioso" at the beginning and the tempo designation for the third movement.
A ritornello is a recurring passage in Renaissance music and Baroque music for orchestra or chorus.
Sonata form is one of the most influential ideas in the history of Western classical music. Since the establishment of the practice by composers like C.P.E. Bach, Haydn, Mozart, Beethoven, and Schubert and the codification of this practice into teaching and theory, the practice of writing works in sonata form has changed considerably.
In music, the term period refers to certain types of recurrence in small-scale formal structure. In twentieth-century music scholarship, the term is usually used as defined by the Oxford Companion to Music: "a period consists of two phrases, antecedent and consequent, each of which begins with the same basic motif." Earlier usage varied somewhat, but usually referred to similar notions of symmetry, recurrence, and closure. The concept of a musical period originates in comparisons between music structure and rhetoric at least as early as the 16th century.
In Western music theory, the term sentence is analogous to the way the term is used in linguistics, in that it usually refers to a complete, somewhat self-contained statement. Usually a sentence refers to musical spans towards the lower end of the durational scale; i.e. melodic or thematic entities well below the level of movement or section, but above the level of motif or measure. The term is usually encountered in discussions of thematic construction. In the last fifty years, an increasing number of theorists such as William Caplin have used the term to refer to a specific theme-type involving repetition and development.
Ludwig van Beethoven's Piano Sonata No. 1 in F minor, Op. 2 No. 1, was written in 1795 and dedicated to Joseph Haydn. It was published simultaneously with his second and third piano sonatas in 1796.
The Piano Sonata No. 14 in C minor, K. 457, by Wolfgang Amadeus Mozart was composed and completed in 1784, with the official date of completion recorded as 14 October 1784 in Mozart's own catalogue of works. It was published in December 1785 together with the Fantasy in C minor, K. 475, as Opus 11 by the publishing firm Artaria, Mozart's main Viennese publisher.
James Webster is a musicologist, specializing in the music of Joseph Haydn and other composers of the classical era. His professional position is as the Goldwin Smith Professor of Music at Cornell University.
The Op. 33 String Quartets were written by Joseph Haydn in the summer and Autumn of 1781 for the Viennese publisher Artaria. This set of string quartets has several nicknames, the most common of which is the "Russian" quartets, because Haydn dedicated the quartets to the Grand Duke Paul of Russia and many of the quartets were premiered on Christmas Day, 1781, at the Viennese apartment of the Duke's wife, the Grand Duchess Maria Feodorovna. Some scholars theorize that the "Russian" quartets were the inspiration for Mozart’s six string quartets dedicated to Haydn, but no direct evidence has been found.
The Symphony No. 21 in A major, Hoboken I/21, was composed by Joseph Haydn around the year 1764. The symphony’s movements have unusual structures that make their form hard to identify. The parts that pertain to sonata form are often hard to recognize immediately and are often identified “only in retrospect.”
A transition is a passage of music composed to link one section of music to another. Transitions often function as a moment of transformation and may, or may not in themselves, introduce new, musical material.
A slow movement is a form in a multi-movement musical piece. Generally, the second movement of a piece will be written as a slow movement, although composers occasionally write other movements as a slow movement as well. The tempo of a slow movement can vary from largo to andante. It is usually in the dominant, subdominant, parallel, or relative key of the musical work's main key.
For music of the Classical period, "interpolation" is defined in the context of a musical sentence or period as "unrelated material inserted between two logically succeeding functions".
